§ 1983 False-Arrest Claims: “Any Crime” Probable Cause and Flexible Jury Instructions on Illinois Obstruction/Resistance

Introduction

In Marion Thomas v. Daniel McAuliffe (7th Cir. Mar. 23, 2026), Marion Thomas appealed the denial of his motion for a new trial after a jury found for Chicago police officers Daniel McAuliffe and Michael Botica (and the City of Chicago) on Fourth Amendment claims brought under 42 U.S.C. § 1983. The case arose from a November 2019 traffic stop in Chicago after officers observed a turn-signal violation, reported smelling marijuana, and then arrested Thomas following his refusal to comply with commands (rolling down the window, placing the car in park, and exiting the vehicle).

On appeal, Thomas challenged: (1) two jury instructions bearing on the legality of the stop and arrest; (2) the denial of a new trial based on allegedly “fabricated” testimony about a “grinder”; and (3) a defense question at trial referencing Thomas’s criminal record. The Seventh Circuit affirmed across the board, emphasizing the “any crime” probable-cause rule for false-arrest claims, broad discretion in crafting jury instructions when read as a whole, and the high bar for new-trial relief based on fraud or prejudice.

Summary of the Opinion

  • Jury instructions (affirmed): The panel held the “Issues” instruction was consistent with the Devenpeck “any crime” rule and therefore not erroneous. It also held the “Authorized Acts” instruction, viewed in the context of the full charge, adequately guided the jury even without an express Illinois-law explanation that “resisting” requires physical resistance.
  • Sanctions/new trial under Rule 60(b)(3) (denied): The panel found no clear basis to treat an officer’s inconsistent terminology (“cutter” vs. “grinder”) as fraud or willful misconduct warranting the extraordinary remedy of a new trial.
  • Criminal record question (harmless): Because the objection was sustained, the plaintiff did not answer, and the jury was instructed that lawyer questions are not evidence, the panel found no prejudicial error.

Analysis

1) Precedents Cited

A. Standards for reviewing jury instructions and obtaining a new trial

  • Saathoff v. Davis, 826 F.3d 925 (7th Cir. 2016): The court reaffirmed that while challenges to jury instructions are reviewed de novo, district courts retain “substantial discretion” over wording so long as the instructions, read as a whole, correctly state the law.
  • O'Donnell v. Caine Weiner Co., 935 F.3d 549 (7th Cir. 2019), quoting Gile v. United Airlines, Inc., 213 F.3d 365 (7th Cir. 2000): The appellant must show both (1) an incorrect statement of law and (2) likely jury confusion or prejudice.
  • Schobert v. Ill. Dep't of Transp., 304 F.3d 725 (7th Cir. 2002), and Fed. R. Civ. P. 51(c): Preservation matters for instructional error; however, the panel reached the merits here because defendants did not press waiver/forfeiture and the district court decided the merits.

B. The “any crime” probable-cause rule for false arrest

  • Devenpeck v. Alford, 543 U.S. 146 (2004), and Holmes v. Village of Hoffman Estates, 511 F.3d 673 (7th Cir. 2007): A § 1983 false-arrest claim fails if probable cause existed for any crime, not necessarily the offense articulated by officers at the time.
  • People v. Fitzpatrick, 986 N.E.2d 1163 (Ill. 2013): Under Illinois law, officers may arrest for an offense punishable only by a fine—supporting the conclusion that a turn-signal violation could supply probable cause defeating a false-arrest claim.

C. Marijuana odor as probable cause (time-sensitive doctrine)

  • People v. Stout, 477 N.E.2d 498 (Ill. 1985), and People v. Hill, 162 N.E.3d 260 (Ill. 2020): At the time of the 2019 stop, the smell of marijuana alone could establish probable cause of an Illinois crime.
  • People v. Redmond, 248 N.E.3d 1026 (Ill. 2024): The panel noted the post-legalization shift—odor of burnt cannabis alone, without corroboration, may not establish probable cause—while treating it as inapplicable to a 2019 arrest.

D. Defining “terms of art” in jury instructions

  • Dawson v. N.Y. Life Ins. Co., 135 F.3d 1158 (7th Cir. 1998), and DePaepe v. Gen. Motors Corp., 33 F.3d 737 (7th Cir. 1994): Failure to define a term of art can create legal error or confusion; the panel used these cases to frame the inquiry but held that no such confusion existed here when the instructions were read as a whole.

E. Illinois obstruction/resistance doctrine

  • 720 Ill. Comp. Stat. 5/31-1 (2014) (and the essentially cosmetic 2023 revision): The statutory basis for “resisting or obstructing” a peace officer performing authorized acts.
  • People v. Kotlinski, 959 N.E.2d 1230 (Ill. App. Ct. 2011): Resisting requires physical resistance; obstruction can include passive acts that impede an officer.
  • Pryor v. Corrigan, 124 F.4th 475 (7th Cir. 2024) (Rovner, J. concurring in part and dissenting in part): Cited for the proposition that obstruction occurs when one materially impedes an officer’s authorized acts.

F. New trial as a sanction and inherent authority

  • Wickens v. Shell Oil Co., 620 F.3d 747 (7th Cir. 2010): Rule 60(b)(3) permits relief when fraud/misconduct prevents a full and fair presentation.
  • Fuery v. City of Chicago, 900 F.3d 450 (7th Cir. 2018): Courts possess inherent authority to sanction willful abuse of the judicial process or bad-faith litigation conduct.
  • Fields v. City of Chicago, 981 F.3d 534 (7th Cir. 2020): A new trial as a sanction is “an extraordinary remedy” reserved for exceptional circumstances.

G. Criminal history and prejudice control

  • Barber v. City of Chicago, 725 F.3d 702 (7th Cir. 2013): Introducing a § 1983 plaintiff’s criminal history can be prejudicial; the panel distinguished this case because no criminal history was actually admitted.
  • Soltys v. Costello, 520 F.3d 737 (7th Cir. 2008): Curative instructions that lawyer questions are not evidence generally negate prejudice absent reason to believe the jury could not follow the instruction.

2) Legal Reasoning

A. The “Issues” instruction and the “any crime” rule

Thomas argued the “Issues” instruction improperly allowed the jury to consider probable cause for crimes other than resisting/obstructing. The panel rejected the premise: under Devenpeck v. Alford and Holmes v. Village of Hoffman Estates, probable cause for any offense defeats a false-arrest claim. The court then identified two independent, legally sufficient probable-cause anchors available on this record:

  • Traffic violation arrest authority: Under People v. Fitzpatrick, Illinois officers may arrest even for fine-only offenses, so the turn-signal violation could defeat a false-arrest claim.
  • Marijuana odor (2019 rule): Under People v. Stout and People v. Hill, marijuana odor alone could establish probable cause at the time of the stop.

The panel’s reasoning underscores a practical point: once the district court properly submits probable cause to the jury, the plaintiff’s false-arrest theory cannot be artificially narrowed to the single offense officers cited at the moment of arrest.

B. The “Authorized Acts” instruction and the level of definitional detail required

Thomas argued the jury needed a more explicit instruction that “resisting” requires physical conduct under Illinois law. The panel acknowledged that omission of “terms of art” definitions can be reversible in some contexts (Dawson v. N.Y. Life Ins. Co.; DePaepe v. Gen. Motors Corp.), but held that the charge as a whole adequately guided the jury because:

  • The jury received an “Underlying Crime—Obstructing/Resisting” instruction tracking the statutory elements.
  • The “Authorized Acts” instruction framed the compliance obligation during a lawful stop (reasonable suspicion), limiting the risk the jury would treat mere speech as resistance.
  • The defense theory did not turn on purely verbal resistance; it focused on refusal to comply and physical conduct (e.g., refusing to exit, going limp/falling, pulling limbs during handcuffing).
  • Under Illinois law, passive impediments can constitute obstruction (People v. Kotlinski), so an instruction tightly focusing on “physical resisting” could have been incomplete given the “obstructing” alternative.

The panel also reinforced that appellate review of jury instructions is holistic, and that district courts maintain substantial discretion over wording (Saathoff v. Davis) so long as the law is correctly conveyed.

C. Rule 60(b)(3) and “extraordinary” new-trial relief for alleged fabrication

Thomas sought a new trial as a sanction under Federal Rule of Civil Procedure 60(b)(3), focusing on Officer Morales’s “grinder” testimony as purported fabrication. Applying Wickens v. Shell Oil Co. and Fields v. City of Chicago, the panel treated relief as exceptional and found the record consistent with confusion over colloquial terminology rather than fraud or willful abuse.

Critically, the district court mitigated any potential prejudice through ordinary adversarial tools: cross-examination, a stipulation that the word “grinder” did not appear in the footage, and informing the jury of the stipulation before closing. These steps supported the conclusion that Thomas had a full and fair opportunity to present his case, making Rule 60(b)(3) relief inappropriate.

D. The criminal record question and cure by sustained objection and instruction

Although Barber v. City of Chicago warns of the prejudice risk from criminal-history evidence in § 1983 trials, the panel emphasized that the question was cut off: the objection was sustained, Thomas never answered, and the jury was instructed that lawyer questions are not evidence. Under Soltys v. Costello, such an instruction typically cures any prejudice absent special circumstances—which Thomas did not show.

3) Impact

A. Reinforcement of “any crime” probable cause in § 1983 false-arrest trials

The decision reinforces a litigation reality for § 1983 plaintiffs: if the record supports probable cause for any offense—traffic, contraband-related, or otherwise—false-arrest claims can fail even if the arresting officer cited a different offense. This encourages plaintiffs to contest the full probable-cause landscape, not merely the stated arrest offense.

B. Instruction drafting: substance over definitional maximalism

The opinion signals that in Fourth Amendment cases where state-law concepts (like “obstruction” and “resistance”) intersect with federal claims, the Seventh Circuit will tolerate less granular definitional instructions if, taken together, the charge steers the jury away from the wrong theory of liability (e.g., treating mere argument as resistance) and matches the parties’ actual trial contentions.

C. Cannabis legalization as a moving target—probable cause is time-bound

By contrasting the 2019 rule (People v. Stout; People v. Hill) with the post-legalization limitation (People v. Redmond), the court highlighted that probable cause turns on the legal regime at the time of the search/seizure. Future civil rights litigation will likely feature intensified disputes over the timeline of cannabis reforms and how quickly “odor-only” doctrines eroded.

D. High bar for “fraud-based” new trials in civil rights cases

The opinion is a caution against attempting to convert credibility disputes or terminology inconsistencies into Rule 60(b)(3) fraud. Unless the misconduct truly prevents a full and fair presentation, courts are likely to treat cross-examination and stipulations as sufficient remedies.

Complex Concepts Simplified

  • Reasonable articulable suspicion vs. probable cause: Reasonable suspicion is a lower threshold that can justify a stop/investigation; probable cause is a higher threshold that can justify arrest or search.
  • The “any crime” rule: Even if officers cite one reason for arrest, the arrest is constitutional (for false-arrest purposes) if objective probable cause existed for any offense.
  • Obstruction vs. resistance (Illinois): “Resisting” generally requires physical resistance; “obstructing” can be passive conduct that materially impedes officers’ authorized actions.
  • Rule 60(b)(3): A mechanism to set aside a judgment for fraud/misconduct that prevented a fair trial—reserved for exceptional circumstances, not ordinary credibility disputes.
  • Motion in limine and “opening the door”: A pretrial order excluding evidence can be revisited at trial if a party introduces material (e.g., video testimony) that makes the previously excluded topic relevant for fairness.
  • Curative instruction: Courts often cure an improper question or reference by sustaining an objection and reminding the jury that lawyers’ questions are not evidence.

Conclusion

Thomas v. McAuliffe is an affirmance with clear doctrinal reminders: (1) § 1983 false-arrest claims rise or fall on objective probable cause for any offense (Devenpeck v. Alford); (2) jury instructions are evaluated as a whole and need not define every nuance where the charge adequately conveys the governing law and the contested issues (Saathoff v. Davis); and (3) extraordinary post-verdict relief—whether framed as fraud under Rule 60(b)(3) or inherent-power sanctions—requires more than inconsistencies that can be tested through cross-examination (Wickens v. Shell Oil Co.; Fields v. City of Chicago).
